PUNCHING-MACHIKE.

Specification of Letters Patent. Paitented Oct. 31, 1911.

Application filed December 14, 1910. Serial No. 597,272.

novel construction and arrangement of.

parts, whereby the osition' of the bag is maintained by a resilient stem supporting said bag and whereby the bag is formed of a single skin of textile material.

The objects of the invention are-to devise a cheap and durable form of punching bag apparatus'and generally to simplify the arrangement of parts in such devices and incidentally increase their efiiciency.

In the drawings, Figurev 1 is a perspective view of the apparatus extending out from a -wall. Fig. 2 is an enlarged sectional view showing the device supported from a wall or ceiling. Fig. 3 is an elevation of the apparatus supported from a floor. Fig. 4 is a sectional perspective detail of the bag.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the bag of pear-shaped form and made of canvas materialfrubber filled or coated with a nonporous-substance. 2 is an air valve in the neck of said valve having a suitable cap 3.

4 are loops secured to the outside of the bag at the neck portion thereof.

5 is a comparatively stifl' helical spring at one end abutting the plate 6 and at the other end encircling the neck portion of the bag 1, said plate 6 having the threaded flange 7 and cord orifices 8 therethrough.

9 is a socket internally threaded and r'eceiving the threaded flange 7, said socket having 12 are cords at one end secured to the loops 4 and at the other end knotted on the inner side of the plate 6, thus securely holding the neck of the bag 1 within the coils of the helical spring 5.

13 is a rebounding ring supported from the flanges 10 secured to the base 11.

the base 11 by the forked spring arms 14, said arms having the flanges 15 at their inner ends secured to the base 11.

'16 is a pedestal on which the base 11 is secured in the use of the bag in a standing position, and in this use of the invention the rebounding ring 13 is not a necessity.

In the useof this invention, the bag 1 is punched with the result that 'it will readily give to the force of the blow, but will quickly'rebound, not only by contact. with the rebounding ring but from the nature of the spring stem, which, as has been described, is a helical spring. The rebounding ring to a limited extent resiliently supported also adds efliciency to this device.

What I claim as my invention is:

1. In a punching apparatus, a bag having a neck portion and a. valve standing out from said neck portion and a long detachable cap secured over said valve, a base plate,

a helical spring at one end abutting said base plate and at the other end inclosing said cap and abutting said neck portion whereby said cap forms a lateral support for the bag, and means extending through the spring for securing said bag, base plate and spring together, thereby supporting the bag,

2. In a punching apparatus, a bag having a suitable neck portion, a helical spring at one end encircling said neck portion, a base plate abutting said spring at the other end, loops secured to said bag and cord members secured to said loops and extending through said base plate and through said helical spring.

3. In a punching apparatus, a reboundingring, a plurality of spring supporting arms secured to said rin and extending therefrom, a basesupportlng said arms and a bag resiliently supported from said base centrally in relation to said ring.

4. In a device of the class described,-in combination, a bag having asuitable neck portion, a helical spring encircling the neck portion of said bag at one end and forming a resilient stem, a base, a socket secured to said base, a plate abutting the other end of said spring and secured in sa1d socket, flexible members connecting said bag and said plate through said spring, a rebounding ring encircling said stem and spring arms plate, a helical spring at one end abutting said base plate and at the other end abut- Signed at file city and district of Monting said bag, means extending through said tree], Quebec, Canada, this eighth day of spring for securing said bag; base plate and- December, 1910.
